The objective of this study was to quantify new bone formation from biopsies of demineralized freeze-dried bone allograft (DFDBA) and freeze-dried bone allograft (FDBA) following ridge and sinus augmentations. Ninety-three patients who received maxillary sinus or ridge augmentation grafts agreed to core biopsies of their grafts when the implants were placed. Samples ranged from 6 to 36 months postgrafting. These samples were sectioned, stained, and examined histomorphometrically, Seventy-two FDBA and 21 DFDBA samples were examined, and the mean percentages of new bone formed were 41.89% and 41.74%, respectively. There was no statistical difference, irrespective of graft site.
